The TI4 Battle Calculator is a visually stunning, advanced tool for Twilight Imperium 4 players, supporting all 25 factions from the base game, Prophecy of Kings expansion, and Codex III (including Council Keleres). It uses a Monte Carlo simulation (10,000 iterations) to calculate win probabilities, expected unit losses, and critical hit chances for space and ground combat. The modern, vibrant design features a sleek interface, card-based layout, and a clear results table. Key features include:

• Support for all 25 factions with specific abilities (e.g., Hacan’s trade goods, Argent Flight’s anti-fighter barrage, Sol’s upgraded carriers).

• Advanced modifiers like anti-fighter barrage, sustain damage, direct hit cards, and Hacan’s trade goods.

• Results are displayed in a stylish, responsive table for easy comparison.

• Exportable results in JSON format for analysis or sharing.

• Save/load battle configurations via local storage for quick setup.

How to Use

1. Select Factions: Choose from 25 factions for each player. Faction abilities (e.g., Sardakk N’orr’s infantry boost, Titans’ PDS upgrades) are applied automatically.

2. Input Units: Enter the number of units (flagship, war sun, dreadnoughts, etc.) and check upgrades where applicable (e.g., Dreadnought II).

3. Apply Modifiers: Enable morale boosts (+1 to combat rolls), anti-fighter barrage, direct hit cards, or Hacan’s trade goods for combat bonuses.

4. Calculate: Click “Calculate” to run the simulation. A loading animation displays during processing, followed by results in a sleek table with win/draw percentages, expected losses, and critical hit probabilities.

5. Save/Load Configurations: Use “Save Configuration” to store setups and “Load Configuration” to retrieve them, streamlining repeated calculations.

The calculator is optimized for all devices, with a vibrant design and smooth animations.

Tips

• Strategic Planning: Test fleet compositions to optimize win chances. For example, Argent Flight’s upgraded destroyers excel against fighter-heavy fleets with anti-fighter barrage.

• Faction Synergies: Leverage faction abilities, like Hacan’s trade goods for combat boosts or Jol-Nar’s -1 combat penalty, to inform your strategy.

• Modifier Impact: Direct hit cards are critical against sustain damage units (e.g., dreadnoughts, flagships). Use them strategically to shift odds.

• Use the Table: The stylish table layout makes comparing win chances, losses, and critical hits intuitive. Focus on high-loss units to adjust your fleet.

• Save Frequently: Save configurations before major battles to revisit scenarios quickly during long TI4 sessions.
